feat: add Phase 4 DinD test templates for HAF apps

Dan Notesteinrequested to merge
feat/phase4-dind-test-templates into develop

Summary

Add composable templates for Docker Compose test environments as part of Phase 4 (HAF App Template Expansion):

New Templates

Template Description
.haf_app_dind_test_variables Standard variables for DinD test jobs (directories, compose config, timeouts)
.haf_app_dind_extract_cache Extract sync cache with shm_dir relocation and blockchain handling
.haf_app_dind_compose_startup Create ci.env and start docker-compose services
.haf_app_dind_wait_for_services Wait for PostgreSQL and PostgREST with DNS fix
.haf_app_dind_compose_teardown Collect logs and cleanup after tests
.haf_app_dind_complete_test Complete ready-to-use test template combining all above

Usage Example 

my-test:
  extends: .haf_app_dind_complete_test
  needs:
    - sync
    - prepare_haf_image
  variables:
    APP_SYNC_CACHE_TYPE: "haf_myapp_sync"
    APP_CACHE_KEY: "${HAF_COMMIT}_${CI_COMMIT_SHORT_SHA}"
    HAF_APP_SCHEMA: "myapp"
  script:
    - ./run-my-tests.sh --host=docker

Reduces Duplication

These templates consolidate common patterns found in balance_tracker and reputation_tracker test jobs:

  1. Cache extraction with blockchain symlink/copy logic
  2. shm_dir relocation for different cache formats
  3. ci.env file creation for docker-compose
  4. Service wait loops with DNS resolution fixes
  5. Log collection and cleanup

Test plan

  • Templates are syntactically valid YAML
  • Test with balance_tracker migration (follow-up MR)
  • Test with reputation_tracker migration (follow-up MR)
